Parametric Cell- different numbers of holes

Hi everyone,

I need to do 2D parametric cell where will change count of holes by hand. Here is example.

Now Im able by changing numbres of holes change diametres, but i dont know how to make there more holes. For example i got 2x2, when i change for 3x3 dimensions are good (58,8 x 54,2), but i have there still just 4 holes not 9. I know that i can make more variantions and uploud them to Components Center, but i want it smart and have just one cell.
